Kills mosquito larvae for up to 30 days.

Mosquito Dunks will kill mosquito larvae before they have a chance to mature into biting adults.

Will not harm people, pets, wildlife or fish.

Easy to Use! Once a month place dunks wherever water accumulates around your home for season-long control of mosquitoes. Each Dunk will treat up to 100 square feet of surface water no matter what the depth. For smaller areas, you can break them in half. Great for use in water gardens, flower pots, bird baths, rain gutters and decorative ponds!
